Cluster Labs - The Home of Linux Clustering
We support many deployment scenarios, from the simplest 2-node standby cluster to a 32-node active/active configuration. We can also dramatically reduce hardware costs by allowing several active/passive clusters to be combined and share a common backup node. We monitor the system for both hardware and software failures. In the event of a failure, we will automatically recover your application and make sure it is available from one of the remaning machines in the cluster. While SYS-V init replacements lik...

Pacemaker achieves maximum availability for your cluster services. By detecting and recovering from node and service-level failures. It achieves this by utilizing the messaging and membership capabilities provided by your preferred cluster infrastructure. If the startup and shutdown of your service can scripted, Pacemaker can improve its availability. Pacemaker can manage clusters of practically any size and comes with a powerful dependency model for accurately modeling your environment.

6.4. Placing Resources Relative to other Resources
http://clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/s-resource-colocation.html
64 Placing Resources Relative to other Resources. Tell the cluster that the location of one resource depends on the location of another one. Colocation has an important side-effect: it affects the order in which resources are assigned to a node. Think about it: You can’t place A relative to B unless you know where B is. So when you are creating colocation constraints, it is important to consider whether you should colocate A with B, or B with A. The placement of resources; they do. Positive values indica...
3.2. Cluster Options

Cluster options, as you might expect, control how the cluster behaves when confronted with certain situations. They are grouped into sets within the. Section, and, in advanced configurations, there may be more than one set. (This will be described later in the section on Chapter 8, Rules. Where we will show how to have the cluster use different sets of options during working hours than during weekends.) For now, we will describe the simple case where each option is present at most once. The number of job...
10.2. Clones - Resources That Get Active on Multiple Hosts
http://clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/s-resource-clone.html
102 Clones - Resources That Get Active on Multiple Hosts. Clones were initially conceived as a convenient way to start multiple instances of an IP address resource and have them distributed throughout the cluster for load balancing. They have turned out to quite useful for a number of purposes including integrating with the Distributed Lock Manager (used by many cluster filesystems), the fencing subsystem, and OCFS2. You can clone any resource, provided the resource agent supports it.

That are possible to configure with Pacemaker. Two-node Active/Passive clusters using Pacemaker and DRBD are a cost-effective solution for many High Availability situations. By supporting many nodes, Pacemaker can dramatically reduce hardware costs by allowing several active/passive clusters to be combined and share a common backup node. When shared storage is available, every node can potentially be used for failover. Pacemaker can even run multiple copies of services to spread out the workload.

Require that the resources be placed on the same node. If you want resources to be started on the same node. In a specific order, you need both an ordering constraint.

103 Multi-state - Resources That Have Multiple Modes. Multi-state resources are a specialization of clone resources; please ensure you understand Section 10.2, Clones - Resources That Get Active on Multiple Hosts. Multi-state resources allow the instances to be in one of two operating modes (called. The roles are called. But can mean whatever you wish them to mean. The only limitation is that when an instance is started, it must come up in the slave role. Your name for the multi-state resource.
